PICTURE-313C631) FOR DISPLAY-MACHINES.

ancers.

. Be it known that I. ALEXANDER FERDINAND Ywzroa, a subject of the King of Sweden, but having declared my intention of becoming a cit zen of the United States, residlng at Davenportfin the county of Scott and State of Iowa, have invented new and useful Improvements in Pict-ui'e ltecords for Display- Machines, of which the following is afull, clear, and exact description.

My invention relates to picture records for display machines such as 'kinematographs, stereopticons, and similar apparatus for projecting pictures and the like'upon a screen. Its object is'to provide means for protecting the pictures from abuseto which it may be subjected and thus greatly add to its longevity.

It is alsoa-n object of 'my invention to provide a record which is simple and durable in construction; which is so compact that a great number of the same may be packed and shipped within a comparatively small space; and which is so inexpensive to manufacture that it can be profitably sold to the user at a comparatively small cost and thus be within the reach of persons in ordinary circumstances.

v a toy or educational appliance. This I acconiplish by the means and in the manner hereinafter fully described and'as more particularly pointed out in the claims, reference being had to the accompanying drawings,

' forming a part of this specification, wherein,

Figure l is atop plan View of half of one of my improved records. Fig; 2 is a central transverse section thereof taken on line 2 2, Fig. 1, and drawn to an enlarged scale.. Fig. 3 is a plan view of a fragmentary portion of a record showing the back layer broken away to disclose the relative arrangements. Fig. 4: is a detail view of one of the pictures re- ,moved from the record. Fig. 5 is a plan view of 'a modified r ecord, in which a fiat film disk is used. Fig. 61s a transverse section taken on line 6-6, Fig. 1, and drawn to an enlarged scale. 1

the same it becomes necessary to mount the transparency in some efficient manner in order that it may be passed through the ma.

6 at equal distances apart. These openings are preferably of the same dimensions as the pictures on the transparencies A, and they are arranged so that their longitudinal diameters are radial from the center of the disk and their longitudinal and transverse boundaries are parallel or at right angles thereto. This plate is of such diameter and the openings so arranged that the picture transparencies will register with the focal axis of the projecting machine when the record is placed therein and operated in connection therewith. When the picture transparencies have been properly placed upon the plate B and the pictures brought into regise ter with the picturewpenings Z), asuitable circular back-plate or retaining disk C is placed over, the opposite side thereof in such manner that the series of concentric picture-openings 0 in this latter plate will register therewith. This retaining disk is preferably of metal of the same diameter as plate spaced apart between the plates B and C, I

prefer to insert a filler D between said plates the edge of which is provided with a series of rectangular-shaped recesses 61 corresponding and alining with the picture openings. This filler is preferably made of straw-board or the like about the same thickness as the transparencies and its outer edge is substan tially the same distance from the center. of the disks as the outer edges of the transparencies. When'assembled in the manner described, the edges of the front and back plates are preferably rolled back upon them: selves to form a circumferential head or reinforceinent selvage E extending entirely around the edge of the same, and the portions of the plates between said head and the outer edges of the transparencies are compressed tightly together to form shoulders e, e, and firmly hold the transparencies in position. Suitable perforations e are placed in this space for intermittently moving the record past the projecting plane, a distance corresponding to that between the centers of said perforations, and a mounting opening F is placed in the center of the record.

Referring to Figs. 5 and 6 of the drawings, 5 represents a transparent picture film, that is preferably circular in shape and is provided near its circumferential edge with a series of equidistant pictures 6, that it is desired to display. This film is usually made of a gelatinous composition and is very flimsy and flexible, and, therefore, liable to buckle or become too distorted to be employed by itself in an apparatus of the type above mentioned. In order to overcome this disadvantage, I prefer to reinforce the same by a suitable metallic plate 3, which in the preferred form is provided with a continuous series of equi-distant picture-openings 4. These openings preferably register with I the pictures on the film, in the same manner as in the preferred form just described, and plate 3 is slightly greater in diameter than the film, and, when the latter has been placed upon it and the pier-u res brought into register with the picture-openings 4, a suitable circular back or retaining disk 7 is placed over the side of the i'ilm opposite the plate. This retaining disk is preferably of bristol or fiber'board (or may be of metal), and is approximately of the same diameter as the plate 3 and it is likewise provided with a series of openings 8 that register with the film pictures and the openings 4 in the plate. After the plate 3, the picture-film 5, and the retaining plate or disk 7 have been properly assembled one upon theother in the order named, the edges of the plate and disk are preferably rolled back upon themselves to.

form a circumferential bead or reinforcement 9 extending entirely around the edge of the same as shown in Fig. 6 of the draw- At the center of the record it is provided with an opening 10, that is reinforced by .an eyelet to bind its edges and-to provide for the insertion of a suitable spindle 11 of the picture displaying machine. and it is also provided with a series of cqui-distant concentric apertures 12 that extend through the plate. film and disk.

In operation, the record is m unted on the spindle of the machine and is then rotated by means ol :1 suitable picl': or other suitable device of the display inn-hine hereinbcfore referred to. 'lhipick enters apertures serif/rim and rotates the record upon its axis a distance sutli ient to bring the pictures back of the projecting lens in 1 prising a plate, a'backing, a plurality of pictures interposed between the same, and a series of perforations passing through said record, between the edges of said record and said openings.

2. A record for display-machines comprising an integral disk-shaped plate having a concentric series of openings therein, a correspondingly shaped backing having a concentric series of openings in register with said first-mentioned openings, and a plurality of pictures of larger dimensions than said openings interposed between. said plate and backing.

3. A record for display-machines comprising a circular plate, a circular backing therefor, a plurality of transparencies interposed between said plate and backing, and a disk shaped filler of less diameter than said plate having a. plurality of recesses in which said transparencies are retained.

5. A record for display-machines comprising a circular plate having a plurality of openings therein. a circular backing therefor having a plurality of openings therein that register with said first-mentioned openings, a plurality of transparencies interposed be tween said plate and backing and filling said openings. and a filler of less diameter than said plate interposed between the inner edges of said transparencies and the center of said plate.

6. A record for displayanachines comprising a circular plate having a plurality of openings therein, a circular backing there for having a plurality of openings therein that register with said first-mentioned openings, a plurality of transparencies interposed between said plate and backing and filling said openings. and a disk-shaped filler of less diameter than said plate interposed between the inner edges of said transparencie and the center of said plate having 1 a plurality of recesses in which said transparencies are retained.
